We are in the process <br />of gathering additional data to better define what the seasonal fluctuations of the groundwater <br />levels were prior to the dewatering activities. NCCI is in the process of contacting an adjacent <br />property owner who may have additional historic groundwater level data that is available for the <br />area. If this data can be obtained NCCI intends to supplement their data with it to more <br />accurately define what the historical seasonal groundwater level fluctuations were prior to the <br />dewatering activities. If the data can not be obtained NCCI will proceed with the data they have. <br />NCCI would like to request an extension to the current December 8, 2006 decision date for this <br />Technical Revision request to January 5, 2007. This extension is required for NCCI to have <br />additional time to attempt to obtain the additional historic groundwater level data and develop <br />the groundwater mitigation plan, and for the Division to review NCCI's response to the <br />adequacy comments, taking into consideration the holiday season. <br />Thank you for your consideration of this decision date extension request. Please feel free to <br />contact me with any questions or comments. <br />Sincerely, <br />/~i! /~v--~' <br />Todd Yee <br />J&T ConsuWn~, Ina <br />Cc: NCCI <br />1400 W 122ntl Avenue -Suite 120 • Westminster CO 80234 • Ph: 303-457.0735 • Fax: 303-920-0343 <br />
